To all 'whom 'it may concern:

Be it known that Ansturm M. BATES, a citizen of the lilnitfni States, residing at Chicago, in the-county of Cook-and State of Illinois, have invented a certain new and. useful Improvement in Cement Packers, of which the'followinfr isn specification.

This .invention relates to a bag or package lllin machine wherein granular material is forel ly fed into-thepaclaage.- It relates particularly to aeeding means. l

My invention is illustrated more or less diagrurnmatically' in i the accompanying drawings, wherein:

Figure l is a iragmentary verticel ei-ossj seetion of the filling machine;

Figure 2 is a view on enenlnrged scale ot'A be 1 aportion nFignre l showing the discharge Figure 3 is en'elevetion `with perte in .section showing the opening and controlling slide;

Figure fl' is an elevation with paits -in section of the impeller;

FigureI 5 is a longitudinal section taken on line 55 of Figui-er1 with parts omitted and showing the impeller 'in position;

Figure this an elevation showing the discharge spout and controlling valve, with 0 parts in section.

Like parte are designated by like char actors throughout.,

A is the hopper i to which the material is fed end from which' it is downwardly B moved by the feeding wheel at. into a chest A2 from which it :tells into the impeller cos-- ing' A. This casing is providedwith removable segment B, which forms about onethird of its bottom. This segment is bolted onto the main casting which forms the remainder of the impcller casing. The par-- ticularorm in which this is accomplished is shownfin Figures and li. The costing B is provided with lateral extensions and at its upper end there is a pai 1l of enlarged perforations B B communicating with narrowed. slots B2 B2. The lower extension has a pairof slots B3 B8. The bolts or screws which hold the segment B in position ere mounted in the main casting and segment B is moved into position so that the heads of the bolts or screws pass through the enlarged holes B. It is then slipped down so that the shank of the bolts or screws more into the narrow slots. The Screws are then tightened and the segment is secured in position.

' The segment B is perforated as at Gand has fastened to it at 'this point e member C', which is provided with. a perforation C* in continuation vof the perforation C. Mounted. so as to slide across the perforation C is a, ,shutter C, provided with a central perforation C4. This shutter is held in position by themember-C and may be moved back and forth across the openin so as lto control the discharge of material therethrough. The member C may be fastened4 to the se ent B'by bolts C5. shown in seeton in 3. A skirt portion C projeotf dovvnvvard from the outer end of the mem 4D is -e removable floor piece lor the im pellercasin It is positioned at the? point at which it has been determined the greatest wear takes place, and it is made removable in order'that replacement can be made. This member is erforated-and is held in position by 'a bolt 5 which passes through it and throu h a positioning. finger D2. The bolt is su ciently tightenedto hold the parts in the position shown, and the set screw D? in the outer end of the' finger D2 is manipulated further to tighten the bolt and to hold the parts more rigidly in position.. This eefv screw Ds also serves to adjust the segment B in position before the sme is finally clamped by means of the bolts in slots B,

is a package holding frame pivoted at E upon a laterally extending rod E which is itselfl pivoted at E. The frame E is supported upon' the ends of the seele beam E4, as at E5. The scale beam E* is pivotally supported upon a knife edge E. The bag or other package is supported in the frame E. The bag, which is preferably of the valve'type, is provided with an opening in its top and is positioned so that the dis charge spout F extends into the 'openi'n As mterial is dischargedlinto the bag whie is sup Vorted upon` the scale, the scale beam is gra ually depressed. The nozzle F; since lit is supported from the frame E, moves with the frame. The nozzle F is located in a valve block F', and about this block F and overlying the impeller casing is an apron F3. The inner end of the nozzle tube` F is chamfered SQ, as to eliminate. anyposl sibility of the material' being projected against an abrupt edge whereby its discharge might be interfered with.

Supported together with the frame E are a pair of brackets G, which carry between them a locking lug G', notched on its lower end as at G2. The u per end of this lug is split and is provi ded)with a dog GB. The operation et this dog will not be described in detail as it forms no part of the present invention. It. is Suiiicient to sa that the member .G' serves lby means of its. notched end G2 to engage the fabric of the bag which is being. iilled and prevent accidental displacement of the same.

H is an iinpeller formed of a split hub each half of which is provided with two laterally extending arms H l The impellet' is mounted upon a driven shaft H2 which is driven from any suitable source of power. The two parts of the impeller hub are fastenedtogether by the screws il H8. To each of Athe arms H is. fastened la blade H4, which has a central oorrugation H seated in a corresponding groove H7 in the` arm H of the hub.` Thus each blade is prevented from twistingwlien'the single bolt Ha which holds it inposition is tightened, yand its position in or-'eut may readily be adjusted by the manipulation of this single bolt. 'lhe central corrugation'H5 serves as a. still'ening means'as Well as a positioning means for the'blade. An elongated slot H is provided for the passage ot l so that .the blade may be adjusted in or out.

llie impeller casing is provided with a lateral extei'ision l, which adjoins a similar lateral extensionl from another impeller casing which :terms part of the same ina-v chine. Since cement or other finely divided inatei-ialfis in the impeller casing it will ciiw eulate through the extension l, and iii order topi-event its escape into the .surrounding aiikor into the bearings or the. machinery a readily applied flexible joint is used to connect the adjoining casing extensions. As here sho'ii, this joiiitis made of flexible tape l2, which may be ot' anysuitable type and iiiay'or may not be painted oi' ginnined. Iii any eventit serves to malte an air tiffht joint and one which may readily be appxlicd and one wl'iich avoids thenecessity of accurately aligned p arts and. carefully fitted and niachinod' joints. The slide C8 is provided with a manual control which includes'the link .l

nnectcd to the slide at. one end and pivotaly connected to the endy lWhich is pivotally c J of a lever arm J2, at its other end. This arm is pivo'ted as atJV and provided with a controlling handle It.

The use'and operation of my inventionare as follows: y l

vleakage or discharge of material ,comprising a central hub at a predetermined oint to control the Weight of material to ev discharged into the package. Material may be fed into the hopper at that time o r it may' be previously be depressed and, the nozzle moving Withit,

the perforation therethrough will gradually' move out of register with the perforation in the bottom of the impeller casing, and thus the amount 'of material discharged will be When the predetermined amount of. material has been discharged into the bag its Weight willbe sutieient completelyto depress the scale beam and thuscornpletely to closethe nozzle opening and to prevent further discharge. The apron about the nozzle assembly, which is also mounted on the moving frame, is provided inorder to prevent the lateral discharge of material which may 'escape during this operation due to leakage, and other causes. When the scale beam has come to rest the controlling handle is operated and the slide is moved across the nozzle opening so as to positively close the same.. The filled ef-the inipeller casing; but since the slide 'has been moved across this o ening no discharge can taire place. Anot ier package is placed in position on thenozzle and the operator then positively opens the slide valve and permits discharge -into the package through the nozzle, and the cycle el operation is repeated. As the bag is filled and the. scale beainis correspondingly depressed the depending lip on the casting C covers the rear or inner opening of `the nozzle, and a Hat face on the casting l" extending above the inner opening of the nozzle revente rom the iinpeller casing into the air as the scale beam descends.
